Facebook groups enable like-minded people to get together and share anything, as well as interact with each other. If you no longer want to be part of a group and receive notifications from it, you can "unfriend," or leave, the group. You will not be able to see the group's activity as soon as you leave the group. You can, however, apply to rejoin the group or ask a moderator to invite you back in.

1. Log in to your Facebook account and click the group that you want to unfriend in the Groups section in the sidebar.

2. Click the gear icon next to "Notifications" and choose "Leave Group."

3. Click the "Leave Group" button to confirm the action and leave, or unfriend, the group. You can check the "Prevent other members of this group from re-adding you" box if you don't want to be re-added to the group.
